So there will be a text field that I disable using the textField.setEnabled(false) method. However later on in the code I want to enable this text field back again. textField.setEnabled(true) does not work at this moment.
How should I address this problem?
Try to create a Jtextfield like instance variables

If I were to print
System.out.println(-Math.abs(-14));
would it print -14 or would it disregard the negative sign on the outside of the Math.abs code?
You will get -14. Please go try your code first to see its behaviour

Use java.util.Set clas instead of list.
Set items = new HashSet<Item>();

So I made a frame for user to key in the name and student id in JTextField. I implemented ActionListener to get the text from the text fields. Now I want to retrieve the text to be displayed in a different frame. How do I do that?
Use getText() method to get whatever was typed in a JTextField:
String text = yourtextfield.getText();
